CVE-2024-39011

Comprehensive Technical Analysis of CVE-2024-39011

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2024-39011 CISA Vulnerability Name: CVE-2024-39011 CVSS Score: 9.8

The vulnerability in question is a Prototype Pollution issue in the chargeover redoc software, specifically in version v2.0.9-rc.69. Prototype Pollution vulnerabilities occur when an attacker can manipulate the prototype of JavaScript objects, leading to arbitrary code execution or Denial of Service (DoS) conditions. The CVSS score of 9.8 indicates a critical severity level, highlighting the potential for significant impact if exploited.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Web Application Input: Attackers can exploit this vulnerability by injecting malicious input through web application forms, API endpoints, or any other user-controlled input fields.
• Third-Party Libraries: If the affected software integrates with third-party libraries or services, attackers may exploit these integrations to inject malicious code.

Exploitation Methods:

• Prototype Manipulation: By manipulating the prototype of JavaScript objects, attackers can alter the behavior of the application, leading to arbitrary code execution.
• DoS Attacks: Attackers can cause the application to crash or become unresponsive by injecting specially crafted payloads that trigger excessive resource consumption.

3. Affected Systems and Software Versions

Affected Software:

• chargeover redoc version v2.0.9-rc.69

Affected Systems:

• Any system running the affected version of chargeover redoc. This includes web servers, application servers, and any other environments where the software is deployed.

4. Recommended Mitigation Strategies

Immediate Actions:

• Patching: Upgrade to a patched version of chargeover redoc as soon as it becomes available.
• Input Validation: Implement strict input validation and sanitization to prevent malicious payloads from being processed.
• Content Security Policy (CSP): Enforce a strong CSP to mitigate the risk of code injection attacks.

Long-Term Strategies:

• Regular Security Audits: Conduct regular security audits and code reviews to identify and mitigate similar vulnerabilities.
• Security Training: Provide training for developers on secure coding practices and common vulnerabilities.
• Monitoring and Logging: Implement robust monitoring and logging to detect and respond to suspicious activities promptly.
